a quick demo CO2 + Telosb

Change following lines in sky/dev/light-sensor.c

#define INPUT_CHANNEL      (1 << INCH_0)#define INPUT_REFERENCE     SREF_0
#define PHOTOSYNTHETIC_MEM  ADC12MEM0
#define TOTAL_SOLAR_MEM     ADC12MEM0

Then, the light sensor channel is redirected into CO2.

I try to creat a new sensor file in Contiki for Telosb, but it alway fails.
Any one know offical documents about this issues? Thanks for the help
